extruder bearing

thingiverse

I designed a 3D printable extruder bearing because existing options were insufficient, so I created my own. For its performance, printing in nylon is recommended due to its inherent lubricating properties. The bearing was specifically designed for use with 1.75mm filament. To make the design more versatile and user-friendly, I revised the OpenSCAD code. Now, when you open the file, the parameter names are self-explanatory, allowing you to customize your bearing easily and quickly. Additionally, I modified the OpenSCAD script to automatically adjust the inner diameter based on the chosen parameters. A version with a triangular hole is also available. When working with the SCAD file in OpenSCAD, you will initially see a list of names that resemble variables. To adjust the size of your bearing, simply modify these variable values by changing the numbers assigned to each name. The term "halfheight" specifically refers to the height of each cylinder and is used for alignment purposes, both vertically within each half-cylinder and for adjusting the total hole depth accordingly. When you alter the value of $fn (short for faceted points), it affects how detailed your bearing model appears when printed. A higher number corresponds to more detailed rendering, while a lower number reduces details, ultimately leading to smoother edges.
